I got into OpenSolaris shortly before Oracle swooped in and killed it. For a long while, I ran OpenIndiana on a server where I work, but I found that it really wasn't friendly to white-box hardware. In particular, it was prone to hiccuping badly if I hot-swapped SATA drives on an AMD AHCI controller. I probably would have had better luck if the system had an SAS HBA for the drives, but that wasn't going to happen. I finally switched it to Ubuntu Server with ZoL, and the hot-swap woes went away completely. As for systemd vs. SMF, I'd take systemd any day over the crawling XML horror of SMF. :)
